1. Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic
tape (400 parts per full reel).
2. Inductance is for the primary, measured at 150 kHz, 0.1 Vrms, 0 Adc.
3. Minimum inductance is for the primary, measured at 150 kHz,
0.1 Vrms, 5 Adc.
4. Leakage inductance is for the primary winding with the secondary wind-
ing shorted.
5. Turns ratios are with the primary and secondary windings connected in
parallel.
6. 1500 Vrms, one minute isolation (hipot) between primary and secondary.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
Connect pin 1 to 2, pin 5 to 6, pin 7
to 8 to 9, and pin 10 to 11 to 12 on
PC board.
